Here is what I have... one site "A" with x domain, 2 dc's one win2k3 and one win2k. The 2k3 handles the dns (with forwarders), dhcp, ad, and third party mail server program... the win2k houses sql database. At a different site "B" I have another win2k machine that is an application server. It was set up before the first site (ages ago) and was set up as a standalone server with it's fqdn belonging to the x domain (our registered name). Should that standalone server now become a member server/dc of site "A" or can it just remain the way it is or will it cause problems because it has the same domain name? I hope that this makes sense. Thanks in advance.
